I have used Mollasses as a fertilizer additive AND a stand alone folair agent for years and it is a great supplement! If you want to try it out I recommend using only Unsulphered Blackstrap Mollasses at a dosage of 1tsp per Gal - Put it in a small bottle with some warm water and shake until mixed, then pour this mixture into a sprayer that is already full of COLD, PH corrected, low ppm filtered water and mix it in, then just spray all you're girls leaves down (Always use the coldest water possible when folair feeding, it not only makes the leaves crisp and ensures maximum absorption before evaporation, it has the added benefit of killing or washing away spider mites on the leaves.). I do this every-other weekend at least a few hours before the end of the dark cycle. It doesn't attract bugs or cause mold as the plants absorb almost everything within that few hours of dark.
A good example of Mollasses in folair is Magic Green from House and Garden. It contains mostly Mollasses and Humeric Acids. They won't tell you this, but anyone who has used it (or smelled it) who has used these ingredients for years could tell you. That being said here's what House and Garden says about application:
"Application: Apply 5-10 ml per liter of spraying solution, 1-2 times per weeks just after the lights have been switched off."
and
"Do not use Magic Green more than once or twice a week. This is to prevent the development of the roots from slowing down, because it is too easy for them to absorb the nutrients though the leaves. use Magic Green only as a booster. .
Application- If the plant leaves are discoloured (veins are too green or too pale). If the nutrients absorption of the roots is disturbed. As a protection against damage by fungi and insects. To give the plant growth an extra booster.
Method- Magic Green is applied by spraying with a plant sprayer. Fill the sprayer with water and add the prescribed amount of Magic Green. Magic Green works within two days.
WARNING: Spray Magic Green when there is NO direct light to avoid burning. Always clean out unused Magic Green from container after applying to plants. NEVER STORE MIXED MAGIC GREEN!!!!!"
Rock On and Happy Growing
